FOSS gamedev and creative worlds

I am using the stand alone Zombie Mob and was wondering what needs to be set to make them spawn in a bit darker light?

--name, nodes, neighbours, minlight, maxlight, interval, chance, active_object_count, min_height, max_height mobs:register_spawn("zombie:zombie", {"default:stone", "default:dirt_with_grass"}, 5, 0, 1, 1, 31000)

Do I need to change minlight, maxlight ?
Is that the (5,0) part of the code?
If so what should I set it to?

Change to:

mobs:register_spawn("zombie:zombie", {"default:stone", "default:dirt_with_grass"}, 0, 0, 1, 1, 31000)

OK Thanks.
